THIS PROJECT IS DEAD.You should no longer use this driver. It is unsupported and outdated.

Overview:

Have you ever wanted/needed to update the SigmaTel/IDT audio chipset drivers on your PC? Neither SigmaTel nor IDT distributes a generic driver for these devices, so users must rely on the OEM to update drivers. And the truth is, this happens only rarely. Therefore, I have created a modded INF for the SigmaTel driver, which will allow for the latest version released by any OEM to be installed on any system with a SigmaTel codec. It supports Windows XP and Vista in both the 32 and 64 bit variants. However, right now only Dell laptops are supported. In the next few weeks, I will add support for all other SigmaTel audio devices which I can find. Note that I do not by any means own all of these devices, and therefore I cannot test them. Therefore, I must count on feedback from users in order to fix whatever problems may occur in the INF. To install the drivers, download the file, extract the contents to a folder on your hard disk, and run setup.exe.

Note: This INF is beta, and therefore may or may not work. Later drivers are available than the one on this link, but I have currently been unable to get those to work.

Thanks, I am using a DELL 1520 with XP 64-bit so I will test this now. I have the Sigmatel 9205.

Edit: It did not work. I used the have disk method and directed it to the modified 64 inf in the WinXP folder, it gave me an error saying that something went wrong during installation but heh I still have sound, not sure what will happens when I reboot though and the driver version hasn't changed yet either.

On my xps-m1330 with Sigmatel 9228 audio codec the installation works fine, but control panel applications doesn't work and loses its original name... now it is **IDS_CPL_NAME
The audio signal doesn't go out from both headphone connetcor (only from the second connector) and now i'm unable to set audio output to 5.1 or double stereo (double headphone)...
Jack sensing dosn't work...

The XPS M1330 probably uses a different configuration INI than the one included in my archive. I have looked at the downloads page at Dell support for your system, and it appears that there are no XP drivers available for your device. You are running Windows XP, are you not? The lack of an XP driver will make it very tricky to get those extra devices working with the modded INF. Also, what are the Device and Subsys IDs of your sound chip? With those, I can figure out which configuration file I should be looking at.

Yes, its normal because you don't use full manual driver installation... you have to go to manual driver list, so you are able to choose IDT audio driver (not signed)...

Yes, DELL recently remove XP driver but I've a backup...

The original driver is ver. 5511... but It has many bugs (stereo mixing and mic controls miss)

Thanks very much, Vitux. I will definitely have a look at this, and see if I can get your special audio features to work properly. I will be busy all morning today though, so it might be a little while.

But i dont know if its the best driver for me, because i'm having some problems with the sound in my laptop. When i listen to music or play some games the sound have some scratches, i dont know how to explain, is like when um listen to a damaged CD. I tried a lot of drives the past two weeks, and didnt solve the problem, and seems that i still have the problem with this driver!!

The driver i was using before is the one that better solve the problem, but not 100%.

I don't know of any other drivers to try, but I do recommend that if you have not already, that you disable PowerMizer on your 8600m GT. If that doesn't work, and you have the Dell Wireless card in your laptop, disable Bluetooth Coexist Mode and all wireless bands except the one you use.
